I'm honored to be a recipient of the 2025 Apple Scholars in AI/ML PhD Fellowship!
Huge thanks to @Apple for the recognition and support, and to all my incredible collaborators, mentors, and especially to my advisor @AnhongGuo for all the support!

Heading to #EMNLP2026! Excited to share two papers on LLM user simulation:
🧠 KnowSim: Simulating how users learn through AI interactions, validated against real human–AI interaction data across different knowledge levels.
🎭 User Role Vector: Investigating assistant bias in LLM user simulators through internal representations and activation steering.
I’m also on the job market! I’d love to connect with folks interested in user simulation, interactive AI evaluation, and oversight for agentic systems. Feel free to DM me!
AI assistants can provide correct, comprehensive information and still be poorly calibrated to the user: too difficult for novices, redundant for experts.
KnowSim is a user simulator that tracks what a user knows and updates that knowledge as the conversation unfolds, so we can evaluate information calibration over multi-turn interactions.
Across 9 LLMs, model rankings changed with the user’s knowledge level.

What if you could 👀 visually skim AI-generated music 🎵 the same way you skim image/video generations?
#𝗧𝗲𝘅𝘁_𝘁𝗼_𝗠𝘂𝘀𝗶𝗰 models are opening up new ways for video creators to prototype soundtracks from prompts, but music is still slow to review, compare, and iterate on.

On the left, a woman in a kitchen follows along with a cooking tutorial displayed on a laptop, showing a man giving instructions. On the right, the same woman wears stylized smart glasses, with an icon suggesting audio instructions, indicating the system’s transformation of video into step-by-step task guidance. Both sides show her cooking diced tomatoes in a pan. The bottom includes colorful square icons and the names of the project contributors: Mina Huh, Zihui Xue, Ujjaini Das, Ashutosh Kumar, Kristen Grauman, and Amy Pavel.

🚨 New on arXiv! 🚨
"Not There Yet: Evaluating Vision Language Models in Simulating the Visual Perception of People with Low Vision"
Can VLMs really simulate what people with low vision perceive?
Our findings: Not quite yet.
